acpi_lpat_raw_to_temp(9)

✨ acpi_lpat_raw_to_temp ✨

okay bestie, welcome to the Kernel API Manual 💅 this one's a lil function called acpi_lpat_raw_to_temp(9) and honestly? she's a glow-up specialist — she takes your crusty raw number and turns it into an actual temperature. no cap. 🦋

---

🌸 NAME 🌸

acpi_lpat_raw_to_temp — returns you a temperature from a raw value, going through the LPAT conversion table 💖 literally the whole personality of this function.

---

🎀 SYNOPSIS 🎀

int acpi_lpat_raw_to_temp (struct acpi_lpat_conversion_table *lpat_table
, int raw );

like, that's the whole signature. she's not complicated, she's just iconic ✨

🫶 ARGUMENTS 🫶

• lpat_table — the temperature_raw mapping table structure, i.e. the ~vibes translation dictionary~ you're passing in. it's the structure that maps temperature ↔ raw, and she needs it. 👑
• raw — the raw value, and it's used as a key to get the temperature out of that mapping table above. so like, you give her the key, she hands you the temp. iykyk 🔑

---

💜 DESCRIPTION 💜

okay so here's the tea ☕ — on success you get a positive converted temperature value back. slay. that's the good ending.

but if things go sideways? you get a negative errno returned in the error cases. so like, don't just blindly trust the number, do a vibe check first 😭 if it's negative, that's not a temperature, that's a complaint.

fr fr, the sign is doing a LOT of work here — positive = actual temp, negative = errno. don't get it twisted 💀
